The Schedule referred to :in these Letters Patent and making part of the same To all whom itmay concern: y

Be it known that I, JULES Roon, of Rochester,

` county of Monroe, and State of New York, have in. vented anew and useful Brace for Holding Up the4 Covers offlrnnks, Pian os, Sewing-Machines, Ice-Boxes, or any chest; and I do hereby declare that the fellowing is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 represents a transverse section of a closed box with the brace on. The red lines show the cover Y Figure 2 represents a top view of a portion of the box with the cover off.

Figure 3' represents a longitudinal section of theY The quadrant or the part'marked A, in the drawings, fig. l, which is fastened t the inside of the cover, is a segmental band, having for centre the centre ot the hinge of the box.

Theinside edge m of the circular band is smooth.

The outside edge n has, from the upper parto, a smooth arc, 0,11, which measures about thirty degrees, and from that point p, to the other end q, there is a certain number of notches. p

At the end q is a pin, h, which prevents the quadrant from going out of the case B, by striking` against a lip at its upper end. The case B'is fastened to the inside of the box. Its use iste receive the quadrant rA to serve as a guard, and to -givea free play'to the quadrant A.

. The lock D, as represented in figs. 3 and 4, 4is composed ofa bolt, a, sliding between the two guides b b, ofthe plate C, having a tooth,`ll, to enter the notches of the quadrant A.

That bolt a is driven forth by a spring, e, fastened to it at one end, f, and fastened stationary to the plate O, at the other end y. When the box is open, the tooth d of the boltawill slip along the teeth of the quadrant A, and if the cover 'lhe-n; if the box must be shut, the bolt a has to be not-ches of the quadrant A.

I do not claim such an arrangement ofla combination hingeV as is embraced in the patent of' Antonia L.
